Ship samples Monday-Thursday to avoid weekend delays. Overnight shipping recommended for all samples.
Most samples ship at room temperature. Use cold packs only when specified. Never freeze whole blood.
Triple packaging: Primary container, leak-proof secondary, and outer shipping container with absorbent material.
Each sample must have: Patient name, DOB, collection date/time, and unique identifier matching requisition.
Complete test requisition form must accompany all samples. Include clinical information and billing details.
All biological samples must be shipped as UN3373 (Biological Substance, Category B).
We provide sterile transport media for chorionic villus sampling (CVS) and products of conception (POC). Request media at least 24 hours before collection.
Request Transport MediaMost genetic tests require EDTA (purple top) tubes. Karyotyping and FISH require Sodium Heparin (green top). Always check specific test requirements before collection.
Never freeze whole blood for genetic testing. Freezing lyses cells and degrades DNA. Store and ship at room temperature unless specified otherwise.
Blood samples should be shipped within 24-48 hours of collection. If delay is unavoidable, store at room temperature (not refrigerated) for maximum 72 hours.
Yes, we accept high-quality genomic DNA (3-5 μg at 50 ng/μL concentration) for many tests. Contact the laboratory for specific requirements.
PGT samples (trophectoderm biopsies) must be shipped on dry ice at ≤ -20°C. Use sufficient dry ice for 48-hour transit and avoid freeze-thaw cycles.
Amniotic fluid and CVS samples must be shipped at room temperature, immediately after collection. Do not refrigerate or freeze. Use transport media for CVS.
PGT-M and PGT-HLA require 4-6 weeks of workup before embryo testing can begin. Parental and affected family member samples must be submitted first.
Yes, we accept samples from international clients. Please contact our client services for customs documentation and shipping instructions.
